I own a domain company.com. All employees in company have gmail accounts. The domain registrar already provides email forwarding, so if I were to send something to bob@company.com, it would be forwarded to bob@gmail.com since I defined it in the web ui.
Now the issue is how can bob send an email from bob@company.com? In gmail, you can add an email account as an alias like so:
, but how can make the backend using postfix? I've read lots of guides, and can't find any information to do this specifically. Some guides tell me how to do it from only one user account, from the shell only, or offloads the task to another smtp server. This is NOT what I want.
Potential answers I have found: http://postfix.state-of-mind.de/patrick.koetter/smtpauth/smtp_auth_mailclients.html This requires a linux account on the server as well. What if I want to have another domain's email forwarded too?

I do know how to use linux. I also know how to start the server. I am able to send emails from the command line as the user I'm currently logged in as, but I don't know what to do next. I'm using amazon ec2 instance and I have port 587 open. EDIT: wow that guy deleted his comment. In summary, he assumed I didn't try anything. – Kevin Hua – 2016-01-20T23:54:54.207
Your question is not clear. Say
bob@company.comreceives a mail which gets forwarded tobob@gmail.comand user wants to reply asbob@company.comfrom his gmail account? is it? – clement – 2016-01-21T06:31:11.393yes, this is what I want. – Kevin Hua – 2016-01-21T06:31:58.960
Do you have a postfix server which can send mails for
bob@company.com? – clement – 2016-01-21T06:33:20.933yes. I can do it from the command line, but I don't know the next steps to set up things like tls, and creating multiple users with passwords to feed to the email client for authentication. – Kevin Hua – 2016-01-21T06:47:32.053
So here are the things you will need to do. 1) setting up SASL auth for users. 2) setting up TLS 3) Configuring your postfix to listen on a public address 4) Configuring gmail to use it. I would suggest you to do one at a time and incase you are stuck,post your
